Removing binary dependencies for telemetry (#186)

This reverse engineers the REST API for Application Insights so that
we no longer need to download / depend on the 3 .dll files that were
necessary to use the Application Insights .NET SDK.

As a result, this also removes the `AssemblyPath` configuration property
since there are no longer any assemblies that this module needs.
